Description
Technical Field
the invention relates to a floating breakwater, in particular to a floating breakwater with wave energy power generation function and a breakwater system.
Background
the floating breakwater is a wave-proof structure which is built on the water surface according to the principle that the wave energy is mainly concentrated on the surface layer of the water body and consists of a floating body and an anchoring system.
Compared with the traditional fixed breakwater, the breakwater has the advantages of low construction cost, easy material acquisition, quick construction, no need of foundation treatment, convenient assembly and disassembly, environmental protection and the like, can be widely applied to deepwater ports, offshore enclosures, artificial bathing beaches, yacht docks, aquaculture bases, military ports and the like, and has wide application prospect and huge market space in the fields of national economy, civil life and national defense safety. It acts as a temporary shield and can play a role in many practical projects, such as: the safety of construction operation of offshore engineering is guaranteed; protecting the sailing of ships entering and leaving the port; as a protective facility when transferring cargo between estuary ships. As a temporary protection facility and a maneuvering wharf in military, the rapid temporary landing and transferring device can realize rapid installation and rapid disassembly, and ensure the rapid temporary landing and transferring of military weapons and materials.
Therefore, attempts have been made to design and build floating breakwaters of different structural forms, the purpose of which is to defend against open sea waves and to attenuate the target wave height to a desired value. However, the floating breakwater of the prior art structure has the following substantial drawbacks:
firstly, the structural style is relatively simple, and the wave-eliminating principle is utilized to be single. The existing floating breakwater generally adopts a square box type or a similar square box type, and only utilizes the wave reflection principle, namely, the wave is attempted to be reflected back to the opposite direction. Generally, the larger the size of a floating body of the floating breakwater is, the larger the wave reflection coefficient is, the smaller the transmission coefficient is, the better the wave dissipation effect is, but the requirement on the anchoring tension of the floating breakwater is exponentially increased, so that the cost of the breakwater is greatly increased.
Secondly, the structural style is relatively simple, which results in single function.

The third opening of the valve body is in sealing butt joint with the second opening of the arc-shaped flow passage, and the fourth opening of the valve body is away from the second opening of the arc-shaped flow passage; a first valve seat used for supporting the first valve core and forming a sealing pair is arranged on the inner wall of the valve body;
a first valve core which is positioned in the valve body and moves in a reciprocating linear way along the direction of the central line of the valve body; a second valve seat used for matching with the second valve core and forming a sealing pair is formed on one side of the first valve core, and a third valve seat used for matching with the third valve core and forming a sealing pair is formed on the other side of the first valve core; the first valve core is provided with a first flow guide hole, a second flow guide hole and an installation cavity for installing the turbine generator, and the second valve seat, the third valve seat, the first flow guide hole, the second flow guide hole and the installation cavity are communicated;
a second spool fixed to the valve body by a first bracket extending from an inner port of the third opening toward the center;
A third valve core fixed to the valve body by a second support extending from the inner port of the fourth opening toward the center;
And, a turbine generator mounted to the mounting chamber of the first spool;
When no external acting force is applied to the first valve core and the first valve core is lowered to the low position, the first valve port between the second valve core and the second valve seat is opened; a second valve port between the third valve spool and a third valve seat is opened; the first valve port and the first flow guide hole are communicated with the third opening of the valve body; the second valve port and the second diversion hole are communicated with a fourth opening of the valve body, and the turbine generator is driven to work by air flow and/or water flow entering from the second valve port and the second diversion hole in a one-way mode;
When external force is applied to the first valve core to drive the first valve core to rise to a high position, the first valve port between the second valve core and the second valve seat is closed; a second valve port between the third valve spool and a third valve seat is closed; the first diversion hole is communicated with the fourth opening of the valve body; the second diversion hole is communicated with the third opening of the valve body, and the airflow and/or water flow entering from the second diversion hole still drives the turbine generator to work in a one-way mode.
the floating breakwater with the wave power generation function has the following working principle:
and the first water storage bin on the first box body and the second water storage bin on the second box body are used for realizing the front and back balance of the floating breakwater and ensuring that a direct current channel formed in a lower cavity of the first box body is completely immersed in water. The second box body is used as a wave-facing end which faces the waves. Waves enter the straight flow channel from the opening of the first opening of the straight flow channel deviating from the arc-shaped flow channel after passing through the floating body, and then form periodic wave motion in the arc-shaped flow channel to drive airflow and/or water flow to flow through the turbine power generation system, so as to drive the turbine generator to generate power.
the specific air flow and/or water flow flows through the turbine power generation system, and the process of driving the turbine power generator to generate power is as follows:
when the airflow and/or water flow in the arc-shaped flow channel is upward, namely waves enter the arc-shaped flow channel, acting force is applied to a first valve core of the turbine power generation system to drive the first valve core to be raised to a high position, and a first valve port between a second valve core and a second valve seat is closed; a second valve port between the third valve spool and a third valve seat is closed; the first diversion hole is communicated with the fourth opening of the valve body; the second diversion hole is communicated with the third opening of the valve body, and airflow and/or water flow enters from the second diversion hole and then is discharged from the first diversion hole, so that the turbine generator is driven to work in a one-way mode to generate electricity.
When the airflow and/or water flow in the arc-shaped flow channel is downward, namely the waves exit the arc-shaped flow channel, the acting force applied to a first valve core of the turbine power generation system disappears at the moment, the first valve core is lowered to a low position due to self weight, and a first valve port between a second valve core and a second valve seat is opened; a second valve port between the third valve spool and a third valve seat is opened; the first valve port and the first flow guide hole are communicated with the third opening of the valve body; the second valve port and the second diversion hole are communicated with the fourth opening of the valve body, and airflow and/or water flow enters from the second valve port and the second diversion hole and then is discharged from the first valve port and the first diversion hole, so that the turbine generator can still be driven to work in a one-way mode.
Therefore, through the self-adaptive movement of the first valve core, the continuous one-way power generation of the turbine power generation system under the action of the fluid is ensured, and the power generation efficiency is high.
therefore, the floating breakwater provided by the invention not only can eliminate waves, but also can realize energy conversion of wave energy and electric energy through wave energy capture, and the energy conversion efficiency is high. In addition, the invention adopts energy conversion wave absorption, and has relatively low requirement on the anchoring tension of the floating breakwater.
preferably, the specific mounting structure of the first casing and the second casing is:
The first box body is provided with a pair of first connecting seats extending outwards, the second box body is provided with a pair of second connecting seats extending outwards and matching the first connecting seats one by one, and each group of first connecting seats and each group of second connecting seats are fixed through a pin.
In the above preferred technical scheme, the first box body and the second box body are fixed in a mode of being rapidly disassembled, and any part of the first box body and the second box body can be conveniently and independently replaced and adjusted.
still more preferably, the horizontal cross-sectional shape of the second casing may be any one of a triangle, a bulbous bow, a semicircle, and a square.
in the above further preferable scheme, the horizontal cross-sectional shape of the second tank body is designed into different shapes, and the second tank bodies with different shapes can be selected to be combined with the first tank body according to different sea areas and different sea conditions (i.e. different wave heights and tide conditions), so as to achieve the purpose of optimizing the power generation wave absorption and protection effects.
Furthermore, the floating body in the floating breakwater with the wave power generation function also comprises an automatic collection system for marine floating objects;
the automatic collection system of marine floater includes:
A conveyor belt assembly located outside and completely covering the opening on the side of the lower chamber facing away from the first opening; the conveying belt of the conveying belt assembly forms an included angle of 30-60 degrees with the sea level and is of a grid structure; a driving roller of the conveyor belt assembly is hinged to a third support extending outwards from the first box body through a first rotating shaft, a driven roller of the conveyor belt assembly is hinged to the first box body through a second rotating shaft, and the driven roller is higher than the driving roller in the direction perpendicular to the sea level;

the impeller is preferably a Savonius impeller.
various garbage floats in the existing ocean are more and more, the garbage floats not only pollute the ocean environment, but also easily block an arc-shaped flow passage in the floating breakwater, and a turbine power generation system cannot normally work. In order to solve the problem, an automatic collection system for the floating objects on the sea is designed in the further technical scheme. The working principle is as follows: when having the wave or flowing, on the floater in the wave current can be impacted the conveyer belt of grid structure, the effect of wave current also can drive the one-way rotation of impeller simultaneously, and synchronous drive roll realizes the linkage, drives the collection storehouse that the conveyer belt was carried the floater to first box again, treats the floater and collects storehouse and scraper contact, drops naturally after being struck off by the scraper and collects the storehouse to reach the purpose of automatic collection floater. Meanwhile, the wave flow filtered by the conveying belt has no garbage floating objects exceeding the size of the grid, so that the arc-shaped flow channel is not blocked, and the normal power generation and wave elimination work of the invention can be effectively ensured.

In the above further technical scheme, the partition plates can play a role in wave breaking, so that the direct impact force of wave current on the floating body is weakened, and the floating body is protected.
still further, the invention provides a floating breakwater with the wave power generation function, and the structure is characterized in that a guide pipe is hermetically butted on a fourth opening of a valve body.

The floating breakwater with the wave power generation function has the following working principle:
The first water storage bin 7 on the first box body 3 and the second water storage bin 12 on the second box body 11 are used for realizing the front-back balance of the floating breakwater and ensuring that the direct current channel 8 formed in the lower cavity 50 of the first box body 3 is completely immersed in water. The second housing 11 serves as a wave-facing end which faces the waves. After passing through the floating body 1, the waves enter the straight flow channel 8 from the opening of the first opening 9 of the straight flow channel 8, which is deviated from the arc-shaped flow channel 6, and then periodic wave motion is formed in the arc-shaped flow channel 6, so that air flow and/or water flow is driven to flow through a turbine power generation system, and further, a turbine generator 27 is driven to generate power.
wherein, the specific air flow and/or water flow passes through the turbine power generation system, and the process of driving the turbine generator 27 to generate power is as follows:
As shown in fig. 4, when the air flow and/or water flow in the curved flow passage 6 is upward, i.e. waves enter the curved flow passage 6, a force is applied to the first valve spool 19 of the turbine power generation system, so that the first valve spool 19 is driven to be raised to the high position, and the first valve port 31 between the second valve spool 21 and the second valve seat 22 is closed; the second valve port 32 between the third valve element 23 and the third valve seat 24 is closed; the first diversion hole 25 is communicated with the fourth opening 18 of the valve body 16; the second diversion hole 26 is communicated with the third opening 17 of the valve body 16, and air flow and/or water flow enters from the second diversion hole 26 and then is discharged from the first diversion hole 25, so that the turbine generator 27 is driven to work in a one-way mode, and further power is generated.
When the air flow and/or water flow in the arc-shaped flow passage 6 is downward, i.e. the wave exits the arc-shaped flow passage 6, the force applied to the first valve spool 19 of the turbine power generation system disappears, the first valve spool 19 is lowered to the low position due to the self-weight, and the first valve port 31 between the second valve spool 21 and the second valve seat 22 is opened; the second valve port 32 between the third valve core 23 and the third valve seat 24 is opened; the first valve port 31 and the first diversion hole 25 are both communicated with the third opening 17 of the valve body 16; the second valve port 32 and the second diversion hole 26 are communicated with the fourth opening 18 of the valve body 16, and the airflow and/or the water flow enters from the second valve port 32 and the second diversion hole 26 and then is discharged from the first valve port 31 and the first diversion hole 25, so that the turbine generator 27 can still be driven to work in a single direction.
Therefore, through the self-adaptive movement of the first valve core 19, the continuous one-way power generation of the turbine power generation system under the action of the fluid is ensured, and the power generation efficiency is high.
therefore, the floating breakwater provided by the embodiment can not only absorb waves, but also realize energy conversion of wave energy and electric energy through wave energy capture, and the efficiency of energy conversion is high. In addition, the invention adopts energy conversion wave absorption, and has relatively low requirement on the anchoring tension of the floating breakwater.
Meanwhile, as shown in fig. 5 and 6, the embodiment further provides a breakwater system, which includes four floating breakwaters of the above structure, and are connected in series to a group of HDPE flexible pipes 33; each adjacent set of floating breakwaters are separated by a buffer spring 34 connected in series to a HDPE flexible pipe 33.

To solve this problem, the above embodiment designs an automatic collection system for the floating objects. The working principle is as follows: when there is the wave or the incoming flow, on the floater in the wave flow can be impacted the conveyer belt 36 of grid structure, the effect of wave flow also can drive impeller 42 unidirectional rotation simultaneously, synchronous drive roll 37 realizes the linkage, drives the collection storehouse 44 on conveyer belt 36 will float the defeated first box 3 of conveyer belt again, treat the floater and to collect storehouse 44 and scraper 43 contact, drop naturally to collecting storehouse 44 after being scraped by scraper 43 to reach the purpose of automatic collection floater. Meanwhile, the wave flow filtered by the conveying belt 36 has no garbage floating objects exceeding the size of the grid, so that the arc-shaped flow channel 6 is not blocked any more, and normal power generation and wave elimination of the embodiment can be effectively ensured.
